Calculus question. complete and explain the following.

We're approximating the area under the graph of the function over the interval [-2, 2] by

Splitting [-2, 2] into 4 intervals gives

[-2, -1], [-1, 0], [0, 1], [1, 2]

Each subinterval has length 1. The right endpoints of the -th subinterval, where , are given by the (arithmetic) sequence

The area of the rectangle over the -th subinterval is

and so the definite integral is approximately

There are well-known formulas for computing the sums of powers of consecutive (positive) integers. The ones we care about are

So we get

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

b
